Method and system to secure the display of a particular element of a markup file

Abstract

A method and system to secure the display of a particular element of a markup file, interpreting a markup file comprising displayable elements, converting the displayable elements of the markup file to at least one image and constructing a modified markup file including the at least one image and a scripting language code adapted to encode links and input fields associated to the image.

1 . A method of handling an interpreted markup file, wherein the interpreted markup file comprises a set of displayable elements including input fields and links and an original scripting language code, the method comprising:
 converting the set of displayable elements of the interpreted markup file to an image;   identifying at least one of the input fields or links in the markup file; and   replacing the original scripting language code by a modified scripting language code, the modified scripting language code being obtained by converting at least one link into markup tags or by converting at least one input field into a markup tag associating at least a part of the image to an input field.   
     
     
         2 . The method of  claim 1 , further comprising:
 altering the image by distorting, greyscaling, re-encoding, resizing, noising, discretizing, resampling or scrambling.   
     
     
         3 . The method of  claim 1 , wherein the image is further divided into a plurality of sub-images. 
     
     
         4 . The method of  claim 3 , further comprising:
 altering one of the plurality of sub-images by distorting, greyscaling, re-encoding, resizing, noising, discretizing, resampling or scrambling.   
     
     
         5 . The method of  claim 1 , further comprising:
 constructing a modified markup file containing the image and the modified scripting language code.   
     
     
         6 . The method of  claim 3 , further comprising:
 constructing a modified markup file containing the plurality of sub-images and the modified scripting language code.   
     
     
         7 . The method of  claim 5 , further comprising:
 interpreting the modified markup file.   
     
     
         8 . The method of  claim 5  wherein the markup file or the modified markup file is an HTML or XML file. 
     
     
         9 . A computer program stored on a computer readable medium, which when executed by a computer device, handles an interpreted markup file, wherein the interpreted markup file comprises a set of displayable elements including input fields and links and an original scripting language code, the computer program comprising instructions for:
 converting the set of displayable elements of the interpreted markup file to an image;   identifying at least one of the input fields or links in the markup file; and   replacing the original scripting language code by a modified scripting language code, the modified scripting language code being obtained by converting at least one link into markup tags or by converting at least one input field into a markup tag associating at least a part of the image to an input field.   
     
     
         10 . A system for handling an interpreted markup file, wherein the interpreted markup file comprises a set of displayable elements including input fields and links and an original scripting language code, comprising:
 a system for converting the set of displayable elements of the interpreted markup file to an image;   a system for identifying at least one of the input fields or links in the markup file; and   a system for replacing the original scripting language code by a modified scripting language code, the modified scripting language code being obtained by converting at least one link into markup tags or by converting at least one input field into a markup tag associating at least a part of the image to an input field.   
     
     
         11 . The system of  claim 10 , further comprising:
 a system for altering the image by distorting, greyscaling, re-encoding, resizing, noising, discretizing, resampling or scrambling.   
     
     
         12 . The system of  claim 10 , further comprising:
 a system for dividing the image into a plurality of sub-images.   
     
     
         13 . The system of  claim 12 , further comprising:
 a system for altering one of the plurality of sub-images by distorting, greyscaling, re-encoding, resizing, noising, discretizing, resampling or scrambling.   
     
     
         14 . The system of  claim 10 , further comprising:
 a system for constructing a modified markup file containing the image and the modified scripting language code.   
     
     
         15 . The system of  claim 12 , further comprising:
 a system for constructing a modified markup file containing the plurality of sub-images and the modified scripting language code.   
     
     
         16 . The system of  claim 15 , further comprising:
 a system for interpreting the modified markup file.   
     
     
         17 . The system of  claim 15  wherein the markup file or the modified markup file is an HTML or XML file.
